I've still got the greyscale .jpg versions of the bump files, and they're not that big... I'll probably just end up lowering the dpi on them... I think I've got them set to something like 200 dpi, which I don't think I really need them to be that high... I don't know how much of a difference it'll make to the look of the texture if I lower it. I'll probably leave the settings for the bump map in the MAT pose settings, and maybe just not load the texture... if you don't have the settings set right the bump maps look really bad... the poor thing looks like she's covered in cement!
